Abstract

Present distributed applications are not typically designed toadapt to changes in network conditions. In addition, network-basedadaptation does not typically consider the requirements of specificapplications and, therefore, may take actions contradictory toapplications needs. This paper presents a cooperative solution inwhich a configurable communication layer is used to adaptcommunication in response to both application requirements andnetwork resource availability. Adaptation decisions are based on(1) payoff functions which capture the application requirements ina functional form, and (2) service availability curves whichrepresent network resource availability. Experimentation withmultimedia applications and a variable reliability protocoldemonstrates the benefit of using payoff-based adaptation.
